I've made some progress and now completed this beast of a cable..
It has the runs sleeved for the other PSU power-on and the Aquaero 5 XT relay. (the long curled up cables)
There were lots of 2-way, 3-way and even 4-way cables.. What a headache!!!!
At least it's all down hill from here, the PCIE's will be a piece of cake after this beastly cable!
